multiport ethernet PCI cards

Looking for hardware suggestions. We're not building a 'Wulf this time,
but a virtual network engineering lab, and these will aid (and abet)
linux-based routers.
I'm looking for 2- and 4-port 100BT cards. Any suggestions, especially
based on experience, are appreciated!
Thanks, gerry
